The latest innovative technology for vertical roller mills: Modular mill with modular drive system and swing mill solutions

Abstract

Currently in the cement industry, the trend is toward ever increasing grinding capacities of individual grinding plants. As a result, plant availability and optimized maintenance concepts are becoming more and more important. A modular mill concept allows the continuation of mill operation even if one roller is not available and provides plant availability. The newly developed modular roller mill for grinding cement raw material, cement clinker, and additives with an installed power of up to 12,000 kW was specifically designed to meet those needs. Large cement plants can now be designed with the one-mill concept for both raw material and cement grinding. Investors plan to install small plants and therefore need to keep their initial investment costs at a minimum. This can be achieved by purchasing just one mill. For this intended use the swing mill with its capability to grind different types of raw materials and clinker, interchangeably, depending on market needs is the appropriate solution.
